"If it’s a combi boiler. Probably the divertor valve. If heat only boiler the three port valve or controller"

"If you’ve got a thermostat, and a reset option, try that first. Alternatively try operating your boiler manually, if that still fails, it could likely be your diverter valve on the boiler."

"Is it a combi boiler or standard regular boiler? If combi then the diverter valve may be the issue and if regular then most probably the zone valve"

Quite possibly you require a new diverter valve, as
it may have become stuck, on a combi boiler it switches from hot water to heating but when it gets stuck you either get one or the other but not both.
Hope that helps."

"This is usually a faulty 2 or 3 port motorised valve which is found by your hot water cylinder."

"Depends on your system, if you have a cylinder then the first place to look is the zone valve."
